Using Home Equity for a Down Payment: What Lenders Look For

Yes, you can use borrowed money — including a line of credit secured by a home you already own — as a down payment, and some lenders will approve it. But a borrowed down payment is not extra buying power. It is a second debt with a second payment, and federal lending rules require lenders to count that payment against you when they size the new mortgage. In practice, borrowing the down payment often lowers the maximum purchase price rather than raising it.

There are two mechanisms people use, two sets of rules that apply to them, and one risk that gets underestimated: putting a second charge on a property you may need to sell. Here is how the mechanics actually work.

Two ways to borrow against home equity

Both are secured debt. The lender registers a charge against your property, which means the house is collateral. The difference is the shape of the repayment.

• A home equity line of credit (HELOC) is revolving. You draw what you need, when you need it, and pay interest on the outstanding balance. At federally regulated lenders these are generally limited to 65% of the appraised value of the property, with total secured borrowing against the same home usually capped at 80%, as the Financial Consumer Agency of Canada explains in its mortgage guidance. Because payments are often structured as interest-only, a HELOC can look cheap month to month while the principal never moves — which is exactly what makes it easy to over-borrow.
• A home equity loan, or second mortgage, is an instalment loan: a lump sum repaid on a fixed schedule, secured behind your first mortgage. Because the lender sits second in line if the property is sold, this money is normally priced higher than a first mortgage, even with the same house behind it. That is not a penalty; it is the cost of the lender accepting more risk.

Those percentage limits matter for a simple reason: the equity you have and the equity you can borrow are different numbers. A home worth a great deal with a large first mortgage may have almost no borrowable room, because the limits are calculated on appraised value, not on your equity alone.

How lenders treat a borrowed down payment

This is where most plans quietly fail. The money is assessed twice: once as a debt, and once as a payment.

• It lands in your debt service ratios. Federally regulated mortgage lenders generally work to a total debt service ratio ceiling of about 44%, according to the Financial Consumer Agency of Canada. A HELOC or home equity loan payment consumes part of that room before the new mortgage payment is even counted.
• It is stress-tested. Under Guideline B-20, federally regulated lenders qualify you at a rate above the contract rate on your mortgage. Your new mortgage payment is therefore assessed at a higher figure than you will actually pay — and so is the payment on the borrowed down payment.
• Compounding changes the real cost. Canadian fixed-rate mortgages are compounded semi-annually by law, so the effective annual cost is slightly higher than the nominal rate quoted. Comparing a line-of-credit rate to a mortgage rate without adjusting for how each compounds and amortises is comparing two different things.
• Lenders trace the source. Documenting where a down payment came from is standard practice, and large deposits appearing shortly before an application invite questions. A signed gift letter from an immediate family member is treated differently from a loan you are obliged to repay, and Canada Mortgage and Housing Corporation publishes guidance on which down payment sources are acceptable for insured mortgages.

One practical consequence: if you draw the down payment loan before you apply, the debt is already visible on your credit file and already inside your ratios. If you draw it after approval but before closing, you may breach a condition of that approval. Either way, tell the lender before you sign anything.

Why stacking secured debt is the real risk

A borrowed down payment usually means two properties, each carrying secured debt. That works while values hold and income holds. The failure cases are specific:

• Both properties sit in the same market. If values soften, the equity supporting your line of credit shrinks at the same time as the value supporting the new mortgage. The debt does not shrink with it.
• You cannot easily unwind. Selling costs money — commission, legal fees, prepayment penalties on a fixed-rate mortgage, discharge fees on the secured line. If you have to sell quickly to clear the down payment loan, the sale may not clear it.
• Vacancy or a rate move breaks the plan. If the second property is a rental, an empty month or a large repair lands on top of two mortgage payments. If the line of credit is variable-rate, an increase in the lender's prime rate raises the payment without any change in your income.
• Refinancing out is not guaranteed. Many plans assume "I will refinance later." Refinancing depends on appraised value, income, credit and the lender's own rules at that future date — none of which you control today.

None of this makes the strategy impossible. It makes it a leverage decision whose downside lands on your home, which is the part to price honestly before you commit.

Down payment sources, and how each is viewed

The pattern in that table is straightforward: money that is genuinely yours costs nothing extra to use, while money you must repay adds a payment and reduces how much mortgage you qualify for.

A checklist before you draw anything

1. Run both scenarios through your budget at a rate higher than today's contract rate — not the rate you were quoted.
2. Pull your credit reports from both national bureaus, Equifax Canada and TransUnion Canada; a free copy is available from each, and errors are cheapest to correct before an application.
3. Ask the lender, in writing, whether borrowed funds are acceptable for the down payment on the specific product you are applying for, and how they want it documented.
4. Get the total cost of borrowing for the down payment loan — rate, fees, appraisal, legal, discharge and prepayment penalties — not just the headline rate.
5. Confirm what happens if you sell the property securing that loan within a few years.
6. Stress-test the plan against one vacancy, one rate increase, or one month of lost income.
7. Have a licensed professional review it: a mortgage professional or the lender for the mortgage, a lawyer or notary for the transaction, and a licensed insolvency trustee if you already carry unmanageable debt. General information like this page is not advice for your situation.

If the plan has already gone wrong

Talk to the lender early. The usual options are refinancing or blending the debt into a new first mortgage, restructuring the payments, or selling in an orderly way rather than a forced one. These are negotiations with real consequences, and they are far easier before a missed payment than after several.

Two consequences are fixed by rule rather than negotiation. A consumer proposal stays on a credit report for three years after completion, or six years from filing, whichever comes first. A first bankruptcy stays on a credit report for six years after discharge. Only a licensed insolvency trustee can administer either one, and trustees are regulated by the Office of the Superintendent of Bankruptcy Canada.

If you have a dispute with a lender, the Financial Consumer Agency of Canada handles complaints about federally regulated financial institutions, while provinces license and supervise most other lenders and each maintains a consumer protection office.

Cheaper ways to close the gap

If the only way to complete a purchase is to borrow the down payment, the honest question is whether that purchase fits. Options that do not add secured debt include buying at a lower price point, saving longer, using gifted funds, or purchasing through an insured mortgage where the federal minimum down payment rules set out by Canada Mortgage and Housing Corporation allow a smaller contribution depending on the purchase price. Each has trade-offs, and none of them is right for everyone.
